...I concur...for all the bikes available it's hard to find the perfect dualsport.
Why Yamaha doesn't make a WR450R is beyond me. Better yet, a WR350!

I'm always tempted when I see a nice EXC400/450 for sale.
But then I ride the 250 and find out it does everything I'm capable of doing offroad. Like, who am I kidding...big power offroad is great, but it can get away from ya (me).
That and WTF, all I do is change the oil on this bike and clean the air filter now and then.
